Description

Technical Field

[0001] The utility model relates to a fixing device for a ventricular drainage tube. Background Art

[0002] An extraventricular drainage tube is needed during extraventricular drainage surgery. Traditional extraventricular drainage tubes are generally glued to the wall with adhesive tape or tied with ropes and hung on the wall during use, and are easy to fall off or fall off during use. For this reason, in the Chinese utility model with the authorization announcement number CN203539841U and the name "extraventricular drainage fixture", an extraventricular drainage fixture is disclosed, including a hanging rod and a height-adjustable hook arranged on the hanging rod, and a measuring tape is installed on the hanging rod, and the measuring tape and the hook are located at the same height. A horizontal rod is provided on the hanging rod, and the measuring tape and the hook are both arranged on the horizontal rod. The measuring tape is slidably connected to the horizontal rod. The hanging rod includes a bottom rod and a top rod that is sleeved in the bottom rod and can move axially relative to the bottom rod, and the hook is arranged on the top rod, and a fastening structure for positioning or loosening the bottom rod and the top rod is provided between the bottom rod and the top rod.

[0003] Although the above-mentioned drainage tube fixing device can improve the accuracy of measurement to a certain extent, there are still some inconveniences. Although the tape measure can move horizontally on the horizontal rod, when the patient is far away from the edge of the bed, the vertical distance is not accurately judged, and the direct distance is large. The tape measure needs to be pulled out for a long distance, which is more laborious to operate. In addition, the top rod can move up and down relative to the bottom rod, and the positioning of the two is achieved through the fastening device. The top rod is heavy, the operation is more laborious, and it is more troublesome.

[0004] Based on the above issues, the applicant conducted research, which resulted in this case. Utility Model Content

[0031] In order to better understand the technical solution of the present utility model, it will be described in more detail below in conjunction with embodiments.

[0032] Referring to Figures 1 to 3 , the ventricular drainage tube fixing device includes a fixing mechanism 30 for hanging the drainage tube and a measuring mechanism for measuring the distance from the drainage tube to the patient (specifically, measuring the vertical distance between the high point of the drainage tube and the patient's head). The fixing mechanism 30 includes a base part 33, a first clamping block 31 arranged on the base part 33, and a second clamping block 32 that can move relative to the first clamping block 31. A clamping space 36 for clamping the rod member 40 is formed between the first clamping block 31 and the second clamping block 32. The second clamping block 32 moves relative to the first clamping block 31 to adjust the size of the clamping space 36. The second clamping block 32 is threadedly connected to the base part 33 through a screw rod 38, and the screw rod 38 can realize the movement and positioning of the second clamping block 32. The second clamping block 32 is arranged at one end of the screw rod 38, and an operating part is arranged at the other end of the screw rod 38, and the operating part facilitates the rotational operation of the screw rod 38. A hanging space 392 for hanging the drainage tube is formed at a position of the screw rod 38 close to the operating part, and the ventricular drainage tube is hung at the position of the hanging space 392 during use.

[0033] In the present utility model, the measuring mechanism includes a straight ruler 10 and a light emitter that can be fixed on the straight ruler 10 or on a rod member 40. In an embodiment, the light emitter can be adsorbed on the straight ruler 10. The straight ruler 10 is provided with graduations 11, and the base 33 is provided with a positioning portion for mounting the straight ruler 10. As a preferred embodiment of the present utility model, the light emitter includes a magnetic mounting portion 21 that can be adsorbed on the straight ruler 10 and a laser pen 20 provided on the magnetic mounting portion 21. As a preferred embodiment of the present utility model, the laser pen 20 is provided with a beam splitter for converting the light into a horizontal line. The beam splitter can convert a dot-shaped light spot into a horizontal line to better determine the reference position for distance measurement of the patient's brain. With this structure, the laser pen 20 is magnetically adsorbed on the straight ruler 10, and the levelness of the laser pen 20 can be calibrated with the help of the graduations 11 of the straight ruler 10. By adjusting the height of the laser pen 20, the light emitted by the laser pen 20 can be made to shine on a predetermined position on the patient's brain, thereby determining the reference line for measurement. Since the light emitted by the laser pen 20 is at a relatively long distance and clearly visible, even if the patient is far from the edge position of the hospital bed, the light can be horizontally irradiated onto the patient's head. During measurement, only the vertical distance between the laser pen 20 and the high point of the drainage tube needs to be measured.

[0034] As a preferred embodiment of the present utility model, the straight ruler 10 is a steel ruler, and the magnet can be directly adsorbed on the steel ruler. The positioning portion is a magnetic portion that can be adsorbed on the straight ruler 10, and the magnetic portion can be a magnet. During use, the steel ruler is leaned against the magnetic portion of the base 33, and the steel ruler can be positioned on the fixing mechanism 30.

[0035] As a preferred embodiment of the present utility model, the magnetic portion includes a first magnetic portion 34 for adsorbing the back surface of the straight ruler 10 and a second magnetic portion 35 for adsorbing the side surface of the straight ruler 10. The first magnetic portion 34 and the second magnetic portion 35 are perpendicularly arranged. Through the arrangement of the first magnetic portion 34 and the second magnetic portion 35, the straight ruler 10 can be better positioned.

[0036] As a preferred embodiment of the present utility model, the base 33 is provided with an extension plate 37. The extension plate 37 is arranged in parallel with the first clamping block 31. The extension plate 37 is provided with a threaded hole, and the screw rod 38 is perpendicularly arranged in the threaded hole of the extension plate 37. As a preferred embodiment of the present utility model, the base 33 and the first clamping block 31 are perpendicularly arranged. As a preferred embodiment of the present utility model, the first clamping block 31, the base 33, and the extension plate 37 are integrally formed.

[0037] As a preferred embodiment of the present utility model, the operating portion is an operating ring 39 formed on the screw rod 38. A baffle portion 391 is formed at the connection of the operating ring 39 and the screw rod 38. The baffle portion 391 can prevent the drainage tube from slipping off, thereby enabling the drainage tube to be hung more stably.

[0038] As a preferred embodiment of the present utility model, the magnetic mounting portion 21 is provided corresponding to the second magnetic portion 35. In the present utility model, in addition to adsorbing the side surface of the straight ruler 10, the second magnetic portion 35 also provides a space for adsorbing the magnetic mounting portion 21. When the laser pointer 20 is not in use, the laser pointer 20 can be adsorbed on the second magnetic portion 35 through the magnetic mounting portion 21, so that the laser pointer 20 is combined with the fixing mechanism 30 and is not easily lost.

[0039] The protection scope of the present utility model is not limited to this embodiment. Any person who makes similar transformations to it shall be regarded as not departing from the protection scope of the present utility model.
